Steroid cell tumors of the ovary are rare sex-cord neoplasms which account for less than 0.1% of all ovarian tumors. They have been divided into two subtypes according to their cell of origin as follows: stromal luteoma, and Leydig cell tumors, and a third subtype with lineage unknown is a steroid cell tumor, not otherwise specified (NOS). The clinical presentation may take many forms, including pain, abdominal distention and bloating, but perhaps the most interesting and noticeable presentations are those related to the hormonal activity and virilizing properties of the tumor. No radiological features of the steroid cell tumor, NOS have been presented in the literature. This report presents the MRI and ultrasonographic findings of a patient having steroid cell tumor, NOS, of the right ovary with metastasis to the uterus.
卵巢类固醇细胞瘤是罕见的性索肿瘤，占所有卵巢肿瘤的比例不到0.1%。根据其起源细胞，它们可分为以下两种亚型：间质黄体瘤和莱迪希细胞瘤，第三种亚型来源不明，为未另行指定的类固醇细胞瘤（NOS）。临床表现可能有多种形式，包括疼痛、腹部膨隆和腹胀，但也许最有趣和最引人注目的表现是与肿瘤的激素活性和男性化特性相关的表现。文献中尚未报道过未另行指定的类固醇细胞瘤的放射学特征。本报告介绍了一名患有右侧卵巢未另行指定的类固醇细胞瘤并转移至子宫的患者的MRI和超声检查结果。
